Javascript date compare

Suppose , you have a Calendar Extender as:

ID="CalendarExtender1"
runat="server"
TargetControlID="TextBox1"
PopupButtonID="btnCalenderPopup"
OnClientDateSelectionChanged="checkDate"
Format="dd/MM/yyyy" />
As shown, implement the OnClientDateSelectionChanged event, and call "checkDate" function. Define this function in javascript as shown:

And then,To find the number of days between any two dates , use following javascript:

var oneDay = 24*60*60*1000; // hours*minutes*seconds*milliseconds
var firstDate = new Date(2008,01,12);
var secondDate = new Date(2008,01,22);

var diffDays = Math.abs((firstDate.getTime() - secondDate.getTime())/(oneDay));

This will give you number of days between two dates.

Thanks.
